Chapter 15 states that only those with 'immense merits' get Sai's darshan. How does the rest of the chapter elaborate on how devotees can receive this vision?

While Chapter 15 opens by stating that attaining Sai's vision, or darshan, is a result of immense merits bearing fruit, it quickly elaborates on the active role a devotee must play. The chapter promises to describe how Sai, being pleased by the "prayer of loving devotees," grants them His vision. The method for pleasing him is illustrated through the analogy of the mother cat and her kittens. As detailed in Chapter 15, the kittens' persistent, loving efforts to cling to their mother ultimately result in her providing nourishment. This suggests that while past merit may be a prerequisite, it is the devotee's present, active, and persistent love—their spiritual 'clinging'—that truly invokes the Guru's grace and makes the darshan possible.
